Overview: .. LK204-25 User Manual Important: Read page 2 before applying power. Connecting LK204-25 Regular Voltage Power is applied to the white or brown four pin SIP connector as follows: Pin 1: +5Vdc Pin 2: = SCL (I²C clock) Pin 3: = SDA (I²C data) Pin 4: Gnd If the sole data source is via the RS-232, the data input is via the DB9 connector. Pins 2 and 3 are not used. Wide Voltage Option (V) .. Power is applied to the white or brown four pin SIP connector as follows: Pin 1: +7 - +15Vdc Pin 2: = SCL (I²C clock) Pin 3: = SDA (I²C data) Pin 4: Gnd If the sole data source is via the RS-232, the data input is via the DB9 connector. Pins 2 and 3 are not used Wide Voltage Option (VPT) Power is applied to the white or brown four pin SIP connector as follows: Pin 1: +8 - +30Vdc Pin 2: = SCL (I²C clock) Pin 3: = SDA (I²C data) Pin 4: Gnd If the sole data source is via the RS-232, the data input is via the DB9 connector. Pins 2 and 3 are not used 2 WARNING: DO NOT APPLY ANY POWER WITH A REVERSED CABLE. DO NOT APPLY AN VOLTAGE OTHER THAN THE SPECIFIED VOLTAGE. DO NOT USE ANY CABLES OTHER THAN THE CABLES SUPPLIED BY MATRIX ORBITAL, UNLESS YOU ARE AWARE OF THE MODIFICATIONS REQUIRED. DO NOT UNDER ANY CIRCUMSTANCES USE AN UNMODIFIED FLOPPY DRIVE POWER CABLE. DB9 Connector Pin Out RS - 232 port: This connector is wired so that a standard “straight through” 9 pin D-sub cable may be used to connect the modules on a standard serial port such as m ports on PCs. Note that this device plies to the EIA232 standard in that it uses signal levels from +/- 3V to +/- 12V. It will not operate correctly at TTL (0 to +5V) levels. ..

Data Out Data In Ground +5Vdc Note: Signals are shown as interpreted by the Liquid Crystal Display module.
Power may be provided to the module by pin 9 of the DB9 connector instead of through the 4-pin SIP.
If power is to be applied using the DB9, it must be a regulated 5Vdc sup
